If I managed to understand your question, you are not clear on how
to discover what the concrete (derived) type of the instance is
and how to get hold of it. If that's the case, then what you use
is dynamic_cast to discover and get the concrete type at runtime.
Section 2.11, "Mapping for xsi:type and Substitution Groups" in
the C++/Tree Mapping User Manual shows how to do this:
